takeWhileSize

inline fun Input.takeWhileSize(
    initialSize: Int = 1,
    block: (Buffer) -> Int
): Unit

Invoke block function for every chunk until end of input or block function return zero block function returns number of bytes required to read next primitive and shouldn’t require too many bytes at once otherwise it could fail with an exception. It is not guaranteed that every chunk will have fixed size but it will be always at least requested bytes length. block function should never release provided buffer and should not write to it otherwise an undefined behaviour could be observed
